Abstract
Abstract An electrial power distribution block is secured to the lower portion of the metal frame of each space-dividing panel. The distribution blocks in an assembly of panels are electrically connected together. Wherever access to electical power on either side of a panel is desired, a slide-in duplex receptacle is mounted on the distribution block on that side. The receptacles interlock with the blocks to provide built-in stress relief, without separate mechanical fasteners, against forces generated by plugging into or removing a plug from the receptacle. The terminals of the blocks are recessed and the receptacle terminals which connect with the block terminals are shielded in plastic sleeve portions of the receptacles. The conductors of both the blocks and the receptacles are molded in place.
